Less is known about adiabatic computing. We have a theory team investigating it seriously. They published an awesome paper where they benchmark the DWave machine.
ok we are at 1hr, time flies when youre having fun, thx so much DS, that was really awesome, esp enjoyed the Q/A relating string theory & QM computing that will be one for history! everyone is free to stick around. also DS suggested further discussion/ feedback on the AMA fmt/ guests etc in the side room chat.stackexchange.com/rooms/43876/daniel-sank-ama-questions
@DanielSank your secret desire is a prj in web programming? whats terrible about it? @Slereah might be able to help with that (he agrees!) & have dabbled in it myself sometimes ;)
@JohnRennie think its ok/ worth further experimenting but wonder if its really necessary when audience isnt that big. the audience was not very vocal in either room :(
There's been talk in the hbar of starting an "Ask me Anything" (AMA) series in which featured guests would answer questions from other users.
These questions would be about physics, the guest's career, or anything else.
What format would work well for a Physics Stack Exchange AMA?
@JohnRennie there has been quite a bit of feedback on that either mod or interviewer. think it could well. alas cannot volunteer for it, think its too much prep/ high profile for me, would encourage other volunteers
@DanielSank dont recall that at all can you be more specific? think its fine for guest speaker to make decisions on fmt, do you think the 2room fmt worked well?
@DanielSank conversations, interviews, AMAs, open forums, (panels!) etc, they all have different flavors, its actually really cool we can support different fmts, would rather not fixate on one fmt myself, maybe try to give guests choice as much as possible... maybe its good to be flexible on it...
@DanielSank yes, that. I was struggling to come up with the right word, but that was my impression of today's event: it's as if you were writing an article about yourself, or in a way, giving a speech. It lacked the interactive feel that I would associate with a chat event or with an AMA (e.g. on reddit, though of course we're not trying to replicate reddit)
@DanielSank think this basically was achieved and the audience was not too active. think maybe the split room idea works better for a more/ very active audience.
@DavidZ speeches are not bad. guests might give speeches. dont have objection to it. think TED and its huge cyber influence etc. but agree speeches are maybe not so in line with the chat room fmt. we should do a live video for speeches maybe. (google hangouts etc)
@DavidZ agreed. was surpised. think we should try to know/ agree on that ahead of time if thats the idea/ intention. dont think it was the wrong decision. think it was a useful experiment (to get response/ data on).
@DavidZ yes, really am hoping to encourage ppl/ guests to use blogs more, have encouraged DS on that in transcripts, ofc hes a natural but so far holding out :)
@DanielSank np, thats basically how it worked if you asked me. liked it as a channel to add running commentary/ notes etc
@DanielSank Honestly, I think it'll be difficult to get that separation the way you want it. Everyone has a different idea of what constitutes big change-of-topic questions, plus people just don't follow directions. Not to say you shouldn't try, but... it will take active moderation to really pull it off.
frankly if you ask me, compared to the other 2 chats, (a small sample) this one was a spectacular success in fulfilling all my expectations (am careful not to have huge expectations! this is cyberspace/ chat etc! only 1hr! all volunteers! little advertising! etc!)
@DanielSank to me one big goal of this all is for stuff just to not blow up lol! there are a zillion things that could go wrong & think nothing did, it all went smoothly :) (how about a n00b saying "yay chat flags" at the beginning! hadnt thought of that one before!) lol
I liked the side room, because I felt invited to ask side questions (even if I expected that they would get ignored because time is so short and precious). And I didn't feel like disturbing anyone...
@ThomasKlimpel agreed, its not so fun to ask questions in main room that are ignored/ skipped :( ... ps thx much for dropping by/ glad to know you havent given up on physics entirely/ have a crazy ref for you/ really wanna discuss with you/ anyone! see Tenev/ Horstemeyer!
Joseph W. Goodman in "Introduction to Fourier optics" uses $\exp[-j 2\pi (f_X x + f_Y y)]$ for the Fourier transform instead of $\exp(-j x \xi)$ as typically used in physics books. This avoids all the hassle with normalization factors, and makes implementation with FFT more direct. Do you have any opinion on this?
They're both fine, but angular frequency is more common in theory calculations, and more convenient because then (d/dt) exp(i omega t) brings out an i omega instead of a i 2 pi f.
@DavidZ ok youre the 1st person who told me that after literally years in here, maybe you can hit mute while am around, regard it as an SE bug that cant fix myself, trying to remember/ be careful but its part of my SE chat habits built up over yrs :(
@JohnRennie Hm, so? A slightly off-topic message was flagged twice, I thought it would be good to clarify the use of flags for those not usually using chat
@DanielSank the style came from my writing (somewhat nonlinearly) on word processors and not thinking thru the entire sentence before writing it, adding clarifying words etc, sorry :(
@DanielSank Yes, it is an opinion, and it is intersting to see how you think about it. It feels mostly like a perspective from a paper and pencil point of view, less so from a software implementation with least amount of surprises point of view.
Einstein said if space time is wrapped then if we start going forward on time axis from a point on time axis then we can get that point back again,so is it possible to wrap spacetime??
@DanielSank btw/ fyi also think the session did very well for an off-main-time session, and suspect it might not be replicated for other ("lower profile") misc guests, suspect you would have gotten more audience at main session time
DANGER!
Do not run this command to 'test' it unless you are prepared for a crash and/or force-rebooting your system.
I was in my Virtualbox running 12.04 trying to compile an app, and while waiting I happened to chance upon a forum where a comment said:
Try :(){ :|: & };:
Fun, too...
Anyhow, once you get the Start menu open I think you can scroll down, find the System accessories heading, click on that heading and you should see the command prompt.
Yeah. I read that. Nice bit. I've had the notion for a long time of wriing an (anonymous) document "What do I do if they called me a crackpot" trying to lay out the steps to getting up to speed and taken seriously.
